# Theft Prevention The root of anti-theft is the protection of private keys, mnemonics or DApp permissions. Therefore, please protect security information such as private keys and mnemonics and comply with the following principles: 1\. Don't scan QR codes and click links from unknown sources; 2\. Don't disclose any security information to others including customer services; 3\. Don't take screenshots or take photos to save the private key or mnemonic phrase; 4\. Do not use wallets or export private keys and mnemonics under insecure conditions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
